Why does the lithium battery winding machine use carbon fiber guide rollers instead of metal guide rollers?
New energy is a hot topic in recent years, which includes the field of lithium batteries. In the production equipment of lithium batteries, stick shafts are used. This equipment is mainly imported, and the guide roller of the winding machine has always been made of carbon fiber. Then let's take a look at the performance advantages of carbon fiber guide rollers!
Carbon fiber rollers for lithium battery winding machines have good carrying performance in actual production. Since the density of the carbon fiber material is only 1.6g/cm3, the overall weight of the carbon fiber guide roller is not high, it is more convenient to use, and the energy consumption is lower. A good standard of dynamic balance.
secondly, the carbon fiber guide roller has extremely high strength, and the tensile strength of the carbon fiber material itself can reach 3500MPa, which makes the carbon fiber guide tube have very good strength performance support in the production of lithium batteries, so even in the case of high-speed operation, The carbon fiber guide roller is not easy to deform. If it is a metal guide roller, there will be obvious deformation at 1376Nm. The carbon fiber guide roller will only break when the torque reaches 4700Nm, which endows the carbon fiber guide roller with strong fatigue resistance.
Furthermore, carbon fiber is resistant to acid and alkali and has relatively low electrochemical properties, which makes the carbon fiber guide roller have better corrosion resistance and correspondingly longer service life.
In addition, the carbon fiber guide roller has very good aging resistance, strong design processability, and a low thermal expansion coefficient. These high-quality properties have further improved the application advantages of carbon fiber guide rollers, which is why they choose to use carbon fiber guide rollers instead. The reason for the metal guide rollers.
